Here comes my turtlehacks, the project is much more time-consuming than I thought. My original idea is to create a scenario that multiple turtles chasing each other, along with the change of turtlr color, moving direction, and background color. But I encounter some difficulty on set the speed within a fixed trail and cannot control all the turtle in the same time when they make a turn. Thus I change to project to make five turtle in a running race. I add the function feature that learned in the function chapter with the random module. The manual is kind of hard to understand for me. I am enlighted by this link a lot.:+<iframe src="https://trinket.io/embed/python/9339862606" width ="100%" height="356" frameborder="0" marginwidth="0" marginheight="0" allowfullscreen></iframe>

Here’s my draft, there are a lot of feature I can fix in the future.
